[0002] In the manufacturing process of steel mesh reinforcement, the bending of the main reinforcing wires is a crucial step, widely used in construction, transportation, power, and other industries. With the acceleration of industrialization and the improvement of production automation, the market has placed higher demands on the processing efficiency, precision, and adaptability of main reinforcing wire bending equipment for products of different specifications. Especially when processing main reinforcing wires with varying diameters and shapes, the flexibility and versatility of the equipment become important factors affecting production efficiency and cost control.

[0003] Currently, most main rib bending devices on the market adopt a fixed bending head structure. The replacement process is complex and time-consuming, often requiring a complete equipment change when processing main ribs of different diameters. This results in low equipment utilization, cumbersome operation, and limited production efficiency. Furthermore, existing equipment suffers from low precision and insufficient automation in achieving multi-angle continuous bending of main ribs, making it difficult to meet the high-efficiency, high-precision processing requirements of complex-shaped main ribs. Therefore, there is an urgent need for a device with a reasonable structure, strong versatility, and the ability to quickly replace bending heads to achieve high-precision continuous bending, in order to solve the technical problems existing in the current technology.

Through a quick-change bending head structure with adjustable height, combined with a hydraulic cylinder, sliding rod, and spring, the device's versatility and efficiency are improved. By using a second motor to drive the three-jaw clamp to rotate, combined with an electric slide rail and cylinder clamping, multi-angle continuous bending of the main rib is achieved, improving accuracy and automation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3This utility model provides an embodiment of a mesh cover main wire bending device with replaceable bending heads, comprising a workbench 1, a first motor 6 fixedly connected to the front side of the inner wall of the workbench 1, a second gear 5 fixedly connected to the drive end of the first motor 6, a first gear 4 meshing with the outer wall of the second gear 5, a rotating ring 2 fixedly connected to the inner wall of the first gear 4 at its middle end, a stop block 3 fixedly connected to the upper end of the rotating ring 2, a base 7 provided on the inner wall of the lower end of the rotating ring 2, a hydraulic cylinder 8 fixedly connected to the rear side of the inner wall of the workbench 1, a drive end of the hydraulic cylinder 8 fixedly connected to the lower end of the base 7, a wedge-shaped groove provided in the middle of the upper end of the base 7, and the inner wall of the wedge-shaped groove slidingly connected... A wedge block 10 is attached, and a bending head 9 is fixedly connected to the upper end of the wedge block 10. A sliding rod 11 is slidably connected to one side of the bending head 9. A limit groove is opened at the upper end of the base 7. The lower end of the sliding rod 11 is slidably connected to the inner wall of the limit groove. A spring 12 is sleeved on the outer wall of the upper end of the sliding rod 11. The upper end of the spring 12 is connected to the lower end of the connecting rod 13. The lower end of the spring 12 is connected to the upper end of the bending head 9. The top end of the sliding rod 11 is fixedly connected to the connecting rod 13. A support frame 14 is fixedly connected to the upper right side of the worktable 1. A cylinder 15 is fixedly connected to the inner wall of the support frame 14. Clamping plates 16 are fixedly connected to the driving end of the cylinder 15 and the corresponding position on the upper right side of the worktable 1.

[0024] Specifically, when using this device, the main reinforcing wire is first passed through the housing 19, positioning it in the middle of the bending head 9. Then, the device is activated, and the system automatically engages the three-jaw clamp 20 to firmly hold the main reinforcing wire. Simultaneously, the cylinder 15 is activated, its drive end pushing the clamping plate 16 downwards to clamp the left end of the main reinforcing wire, preventing vertical displacement during bending. The left and right positions of the main reinforcing wire are limited by the bending head 9 to ensure stability. Once the main reinforcing wire is firmly clamped, the system activates the first motor 6, which drives the second gear 5 to rotate. The second gear 5 meshes with the first gear 4, thereby driving the first gear 4 to rotate. The rotating ring 2 and the stop block 3 connected to the first gear 4 also rotate accordingly, precisely bending the main reinforcing wire.

[0025] When it is necessary to bend main reinforcing wires of different diameters, simply activate hydraulic cylinder 8. Hydraulic cylinder 8 pushes base 7 upward, causing bending head 9 to rise to a position higher than the worktable 1. At this time, pull connecting rod 13 upward, causing sliding rod 11 to move upward against the resistance of spring 12, so that its lower end disengages from the limiting groove on base 7. Bending head 9 can then be moved forward along base 7 and removed, and replaced with a bending head 9 that matches the current main reinforcing wire diameter. This structural design makes bending head 9 replacement quick and convenient, greatly improving the applicability and work efficiency of the device.

[0026] Reference Figure 1 and Figure 4An electric slide 17 is fixedly connected to the right side of the workbench 1. A sliding plate 18 is slidably connected to the inner wall of the electric slide 17. A housing 19 is fixedly connected to the upper end of the sliding plate 18. The right end of the three-jaw clamp 20 is rotatably connected to the left side of the housing 19. A first synchronous wheel 21 is fixedly connected to the middle end of the three-jaw clamp 20. A synchronous toothed belt 22 is meshed with the outer wall of the first synchronous wheel 21. A second synchronous wheel 23 is meshed with the inner wall of the lower end of the synchronous toothed belt 22. The right side of the second synchronous wheel 23 is fixedly connected to the drive end of the second motor 24. The lower end of the second motor 24 is fixedly connected to the inner wall of the housing 19.

[0027] Specifically, if multiple continuous bends of the main reinforcing wire are required, after the first bend is completed, the system automatically controls the cylinder 15 to release the clamp on the left end of the main reinforcing wire. At this time, the electric slide 17 starts, driving the housing 19 and the three-jaw clamp 20 to move to the left, thereby moving the main reinforcing wire a certain distance to the left. Then, the second motor 24 is started, its drive end drives the second synchronous pulley 23 to rotate, and transmits power to the first synchronous pulley 21 through the synchronous toothed belt 22, thereby driving the three-jaw clamp 20 to rotate, causing the main reinforcing wire to rotate through a certain angle. By performing the bending operation again, multiple complex trajectory bends of the main reinforcing wire can be achieved.

[0028] Working principle: When using this device, first pass the main reinforcing wire of the mesh cover through the housing 19 and place it in the middle of the bending head 9. Start the device, and the system will activate the three-jaw clamp 20 to hold the main reinforcing wire and activate the cylinder 15. The driving end of the cylinder 15 pushes the clamping plate 16 downward to clamp the left end of the main reinforcing wire, preventing the main reinforcing wire from moving up and down during bending. The left and right directions are limited by the bending head 9. After the main reinforcing wire is clamped, the system will start the first motor 6, which drives the second gear 5 to rotate. The second gear 5 meshes with the first gear 4, so the first gear 4 rotates accordingly. The rotating ring 2 and the stop block 3 rotate accordingly to bend the main reinforcing wire. When multiple continuous bends are required, after the first bend is completed, the system control cylinder 15 releases the clamp on the left end of the main rib wire, and moves the box 19 and the three-jaw clamp 20 to the left through the electric slide 17, causing the main rib wire to move to the left. Then, the second motor 24 is started, and the drive end of the second motor 24 drives the second synchronous wheel 23 to rotate. Through the transmission of the synchronous toothed belt 22 and the first synchronous wheel 21, the three-jaw clamp is driven to rotate, thereby causing the main rib wire to rotate at an angle, and then the bending operation is performed, thus realizing the bending of complex trajectories. When the diameter of the main reinforcing wire to be bent is different, simply start the hydraulic cylinder 8. The hydraulic rod drive end pushes the base 7 to move the bending head 9 upward. When the bending head 9 is higher than the worktable 1, simply pull the connecting rod 13 upward to move the sliding rod 11 upward and stretch the spring 12. When the lower end of the sliding rod 11 disengages from the limiting groove at the upper end of the base 7, the bending head 9 can be slid forward and removed. Replace it with a bending head 9 of the same diameter as the main reinforcing wire. This setting allows the device to quickly replace the bending head 9 to adapt to main reinforcing wires of different diameters.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
